Year


Contains information about the specific year covered in the span of the data request.  Attribute YearNumber can be used to parse the full response.  Summary insolation fields represent the total for the portion of the year covered in the data request.  For instance if the StartTime = “2011-11-11T00:00:00-08:00” and the EndTime = “2011-11-13T00:00:00-08:00”, the summary fields will only return total insolation between StartTime and EndTime and not for the full calendar year (in this case, 2011).

YearNumber

The specific year corresponding to the insolation summary.

Possible values: An integer such as 2011.  Possible range: 1998 to present year.

PartialYear

Attribute indicates to the client whether the period of measure includes all possible values in the specified summary YearNumber.  If the period of measure is complete, the attribute will not be returned.

Possible values: true only.  Otherwise, PartialYear will not be included.

TotalGlobalHorizontalIrradiance

The total insolation incident on a horizontal plane for the specified YearNumber. Units in Wh/m^2.

Possible values: A float value such as 3622.

TotalDirectNormalIrradiance

The total insolation incident on a plane normal to the sun for the specified YearNumber. Units in Wh/m^2.

Possible values: A float value such as 1455.
